Route Comparison

The Route Comparison APIs can help you plan routes by considering the time and distance between a series of locations. These APIs include:

  • Drive Time Polygon (Isochrones), which retrieves a polygon of the location coordinates that can be reached from a center point within a specified driving time in minutes.
  • Route Matrix, which returns the travel time and distance for a matrix of origins and destinations.


To call the Route Comparison APIs, you must have a PC*Miler Web Services API key. Route Matrix also requires an add-on license.
